The GISIS entry above is everything GISIS has on this killer casualty.
Presumably, it is from the flag state, Liberia.
It tells us just about nothing.
If there is an investigation report,
GISIS does not have it, nor can we find it.
Obviously, collision reports should give the tracks,
the conditions, communications, damage data, etc, etc,
whatever is known about the casualty.
But we have nothing other than 'human error'.
